Title: Volumetric Filling and Capping Machines.
IPC: G01F11/04
Filed: 1967-12-21
Abstract: 1,184,679. Filling containers; container filling machines; dispensing measured quantities of liquids. OLINKRAFT Inc. 21 Dec., 1967 [3 Jan., 1967], No. 58156/67. Headings B8C, B8N and B8T. Containers, e.g. bags 83, each carrying a plug (85), Fig. 6 (not shown), in a neck 84, are presented manually to an opening and filling assembly where each container is opened and moved to a filling nozzle (140), Fig. 7 (not shown), to receive a measured volume of liquid, e.g. milk, from a tank 10 which contains a piston 24 reciprocable to discharge liquid from outlets 63, 66 at opposite ends of the tank. A second filling nozzle and filling and opening assembly is provided under the second outlet from the tank. The piston 24 has a ring 31 capable of sensing a magnetic field from each of two switches 41, 42 and thereby reversing the direction of the piston by energizing a main switch to reverse a liquid valve (70), Fig. 2 (not shown), in the supply pipe to the tank. Liquid is then supplied to the appropriate face of piston 24. The members 41, 42 are adjustable to vary the volume of liquid delivered. Filling operation.-A bag is placed so that two fingers on the end of a capper arm 95 engage the neck 84 under a flange 88; also a flange (86) on the plug engages a groove in a stationary copper plate 92. When a starter button 111 is pressed the capper arm is lowered to disengage the plug from the neck, then rotated and raised so that the neck engages the filling nozzle. After filling the procedure is reversed so that the plug is re-positioned in the neck. Removal from the capper arm is by a kick-off arm (146), Fig. 4 (not shown). Control of the filling operation.-Vertical and rotational movement is via a switch cam plate 120 co-operating with impulse switches 123 and 142 and controlling air-cylinders 106 and 124. After the bag is filled the switch 41 stimulates a filler valve control box 144 and also triggers the return movement of the capper arm. Removal of the bag from the capper arm 95 is by the initiation of a similar cycle at the second outlet activating a kick-off air-cylinder (145).

Title: Method of growing semiconductor rods from a pedestal
IPC: C30B15/16
Filed: 1969-12-04
Abstract: 1,249,537. Crystal pulling. DOW CORNING CORP. 4 Dec., 1969 [3 April, 1969], No. 59190/69. Heading B1S. [Also in Division H1] A semiconductor rod 31 of electrically conductive material, e.g. silicon, germanium or aluminium oxide, is grown by withdrawing continuously a seed crystal from the coolest part of a molten pool maintained in the top of an axially rotating vertical cylinder 17 of the material in a chamber 10 wherein a vacuum of at least 10<SP>-4</SP> Torr is maintained. The pool is maintained using an annular electron beam 21, the centre B of the annulus 61 defined by the intersection of the beam and the top surface of the cylinder being offset from the centre C of the cylinder's surface by at least 2.5% but not more than 25% of the diameter of the cylinder, so that a first portion of the annulus is in tangential juxtaposition with the perimeter of the cylinder and a second portion is diametrically on the opposite side of the centre C from the centre of the annulus. As the cylinder rotates, e.g. at 2-100 r.p.m., every portion of its upper surface is thus exposed periodically to the electron beam and melted. The seed is generally pulled from the centre of the annulus. As shown, the electron gun is annular and the beam is focussed by coils 27. The block may be moved upwards as the rod is pulled whereby the top surface of the cylinder remains horizontally stationary.

Patent GB-743946-A (GB)
Abstract: 743,946. Preparing photographic emulsions. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 11, 1954 [Aug. 24, 1953], No. 23253/53. Class 98 (2). A photographic emulsion containing aqueous gelatino-silver halide dispersed in an incompletely water-miscible liquid is dehydrated, at least in part, by mixing it with a dehydrating agent and separating the emulsion from the dehydrating agent containing the water. Dehydrating agents specified are calcium chloride, sodium chloride, lithium chloride monohydrate, potassium nitrate, sodium sulphate, sugar, silica gel and alumina gel. The dehydrating agent containing the water may be removed by decanting or filtering, or, when an aqueous liquid layer is formed, by running it off from the emulsion. In the case of sodium sulphate, it is preferred to heat the mixture above the transition point of the hydrated sodium sulphate, allow the liquid to settle, cool to solidify the hydrated layer and decant off the emulsion. Suitable incompletely water-miscible liquids are xylene, tetrahydronaphthalene, benzene, toluene, carbon tetrachloride, monochlorobenzene, and ethylene dichloride. Such liquids may contain in solution a film-forming binder, for example a cellulose ether as in Specification 718,404, and such binder may be added before or after dehydration. The gelatino-silver halide emulsion may be a mixed emulsion such as a mixture of three emulsions sensitized to blue, green and red light respectively and each containing a colour former. Such emulsions may be separately hardened, and emulsified in the same or different incompletely water-miscible liquids and then mixed together before dehydration.

Title: Improvements in and Relating to the Measurement of the Moisture Content of Air
IPC: G01N25/64
Filed: 1979-06-14
Abstract: A method is described for producing a signal dependent on variations in the moisture content of air simply and without reference to hygrometric tables. The method consists of maintaining the dry bulb temperature of the air at a substantially constant value not below the dew point and measuring variations in the wet bulb temperature of the air by means of a wet bulb thermometer 14, e.g. a thermocouple. The constant dry bulb temperature may be maintained by an enclosed water bath 12 through which the air duct 8 passes. The evaporating surface of the thermocouple includes a microporous metal known as foam metal (U.K. Spec No. 1464302) which is also used in a guard ring 20 surrounding the thermometer. The ring and thermometer are intermittently flushed with water via valve 22, pipe 24 and nozzles 26. <IMAGE>

Title: Building Dressing Board
IPC: E04C2/40
Filed: 1980-05-08
Abstract: A building dressing board is provided which is flexible and relatively light in weight by virtue of a relatively thin backing or body part (which may be of concrete) to which are affixed surface members (shown as plates - of brick, clinker, concrete or other rigid material) so arranged that grooves are formed between them, and by virtue of the flexibility of a reinforcing or bonding material which bridges the grooves and is elsewhere embedded in the backing or body part. The reinforcing material may be of metal (e.g. galvanised sheet steel) reticulated where embedded but intact where it bridges the grooves and serves for fixing the building board to a building structure (e.g. by means of screws or by welding.) After the fixing the grooves are filled with a jointing substance, so that a concealed fixing of the board is accomplished. The surface members and the backing or body part may, if desired, be formed integrally of one and the same material. <IMAGE>

Title: Plug assembly and method of plugging a passage
IPC: F16L55/13
Filed: 1981-02-13
Abstract: An assembly for plugging a passage such as an oil gallery in a machine, comprises a sleeve 12 and a stem 14 which extends through the sleeve. The stem has a shank 26 one end of which projects from an end of the sleeve and the other end of which is attached through a breakneck 30 to an enlarged hollow head for expanding the sleeve. By pulling the shank while supporting the sleeve the head can be drawn into the sleeve (Figs. 7-9 not shown), expanding the sleeve into gripping and sealing engagement with the wall of a passage, the head undergoing wiredrawing if necessary until the breakneck reaches the first mentioned end of the sleeve. A head skirt can then be deformed outwardly into engagement with a shoulder 80 of the sleeve to prevent the head being removed in the opposite direction, and the breakneck can then be broken to allow removal of the shank, leaving the expanded sleeve with the head within it plugging the passage. <IMAGE>
